Sharpening Teeth
DO NOT allow any tooth to wear too much before sharpening.
Discard any tooth that has lost more than 1/8” of original bite.
Remove the tooth from the cutting wheel to be sharpened.
Tooth Sharpening Guidelines:
1. Obtain an unused tooth for comparison.
2. Discard any tooth that has lost more than 1/8” of original
bite, whether lost through usage or grinding.
3. Grind off a minimal amount from the end, just enough
to restore the original taper and radius on the end. The
end of the cemented carbide tip and the end of the steel
shank should be flush after grinding.
Cutter Wheel Bearings
Lubricate
Lubricate both cutter wheel bearings zerks(1) fitting DAILY.
There is a cutter wheel bearing on each side of the cutter wheel.
• Fill with high-temperature (NLGI 2) grease until you can
visually see the old grease purge itself out all the way
around the seal diameter and new grease beginning
to purge out.
This will ensure that the dirt and debris that gets collected
inside the seal area is flushed away from the internal bearings
thus providing longevity to the bearing and races.
Hydraulic Oil
The hydraulic oil tank (reservoir) (2) is located next to the
battery. The oil level can be determined by a visual check
(3). The oil level should be 1-1/2” to 2-1/2” from the top of
the reservoir or just touching the hydraulic dipstick. Add oil
Maintenance
NOTICE
Sharpening cemented carbide cutting teeth requires
a special process. Have your teeth sharpened only
by a qualified machinist for obtaining a proper edge
and to avoid injury.
NOTICE
Replace oil if it smells burnt or appears to be dirty.
Use only clean, fresh hydraulic oils, free of bubbles.
(bubbles indicate low hydraulic oil level.)
